ROBERT DIAMOND MAYO AND ROBERT DAVID MAYO, OIE CLEVELAND, OHIO.

SANITARY TOILET-SEAT.

Application filed April 12, 1915.

To all whom it may concern:

Be it known that we, ROBERT DIAMOND MAYO and ROBERT DAVID MAYO, citizens of the United States, and residents of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Sanitary Toilet-Seat; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification. 7

This invention relates to toilet appliances, and particularly to disinfecting means for toilet seats, but is not restricted to such use as it may be used in any connection for which it may be adapted or appropriate.

An object of our invention is to improve upon the sanitary toilet seat described and claimed in United States Letters Patent No. 1,050,283, issued January 14, 1913, whereby to enhance the practicability and commercial value thereof.

A further object of the invention is the provision of simple and eflicient means which is automatically operable by a predetermined movement of the toilet seat to permit the discharge of a predetermined quantity of a disinfecting or antiseptic ma terial, in liquid or other suitable form, into suitable position to disinfect one side of the toilet seat preparatory to subsequent use.

A further object of the invention is the provision of simple and efiicient means which is operable to discharge a disinfecting liquid in. spray or vapor form against a surface of a toilet seat when in one position of its movement.

Further objects and advantages of the invention will be apparent from the following detailed description thereof.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,

Figure 1 is a top plan view of one embodiment of our invention, with the seat in lowered position and with parts broken away. Fig. 2 is a side elevation thereof showing,

in dotted lines, the toilet seat raised and partly turned. Fig. 3 is an enlarged central vertical section of the invention with the seat raised, and with parts broken away. Fig. i. is a central vertical section of the invention on the line 00, w in Fig. 1. Fig. 5 is an enlarged detail of the seat and disinfectant liquid controlling parts with portions broken away. Fig. 6 is a similar view of the air pressure creating means of the invention. Fig. 7 is an enlarged front elevation of the parts controlling the turning of the seat, etc, with the seat shaft in section. Fig. 8 is an enlarged sectional detail of the seat receiving trough, the seat resting thereon and the vapor discharging means within the trough. Fig. 9 is a detail of the pump locking means.

Referring to the drawings, 1 designates a closet bowl on the top edge of which is mounted, in any suitable manner, a channel or trough member 2, which forms an end less channel over the upper edge of the bowl, which channel conforms in shape to the toilet seat. The trough 2 is preferably made separate from the bowl 1 and removably secured thereto by spring clips or fingers 2.

The toilet seat 3 is mounted for raising and lowering movements and also for reversing movements to enable opposite sides thereof to be successively placed in upright 0r usable position. This feature of our invention is described and broadly claimed in said former Patent No. 1,050,283, and will not therefore be claimed by itself in this case.

The seat 3 is provided with a rearwardly extending shaft 4, which is journaled for rotary movements in the forwardly projecting arm of a Tshaped bracket 5, the cross arms of which are journaled adjacent to their ends in the side walls of a boxing 6, which is secured at its forward side, as at 7 (Fig.1), to the rear side of the trough member 2, or it may be supported in any other suitable manner as desired. The shaft 4 is provided in an opening in the bracket member 5 with a cam member 4, which coacts with a spring 7, that is carried by the bracket 5, the spring and cam serving to resist a turning of the seat to reverse the position of its faces. The cam l has the sides thereof, which are parallel with the opposite sides of the seat, elongated to assist 3 until it has reached a predetermined point in its raising movement and to prevent a lowering thereof when only partially turned, the shaft 41 is flattened at opposite sides thereof between the bracket 5 and the seat 3, as shown in Fig. 7, and such flattened portion is disposed within a slot 8 in the front side and cover portion 6 of the boxin g 6, which portion 6 is preferably curved in substantially an arc that is concentric with the swinging axis of the seat. The slot 8 coacts with the flattened sides of the shaft tic to prevent a turning of the shaft until the shaft hasbeen raised into the upper enlarged end portion 8 of the slot, which is of suitable size to permit a free turning of the shaft therein. It is thus evident that the seat can only be turned when its shaft is raised into the enlarged portion Sof the slot 8 and that it must be given a complete half turn in order to permit the seat to be lowered. This prevents the seat from falling back upon the edge of the trough 2 when the seat is only partially turned and thereby causing injury to the edge of the trough.

The seat 3 is provided wit-h like upper and lower face portions 9, 9 of wood, pressed fiber, or other suitable materialpand these portions are secured to opposite sides of a metal strip 10, by screws 11, or in any other suitable manner. The metal strip 10 has its edges projected beyond the inner and outer edges of the seat to adapt them to rest upon respective upturned edges of the trough or channel member 2. Each facing portion 9 of the seat is of less depth than the depth of the trough member 2 so that such facing portion will project only a short distance into the channel member when the seat is resting thereon. A handle 12 is provided at the forward or feed end of the seat 3 to facilitate a. raising and turning of the seat.

Projecting axially in opposite directions from the bearing portions of the bracket 5 are the shafts 13 and 1 1. Fixedlyproject ing from the shaft 13 is an arm 15,the outer end of which is connected to a plunger rod 15, the plunger of which works in a dashpot 16 that is carried, in the present instance, by a bracket 17 secured to the trough 2. The bracket 17 is also shown as being carried in part by the shaft 13. The dash-pot 16 is intended to contain oil, or other suitable liquid, to cooperate with the plunger to retard the lowering movements of the seat 3, as is well understood in the art.

A magazine 18 for containing a disinfectant or antiseptic material is disposed within the trough member 2, and, in the present instance, is shown as comprising a tube, which is disposed in the bottom of the trough and extends entirely around the same. The magazine has nozzles 19 projecting at intervals therefrom. The nozzles 19, in the present instance, are shown as being in the form of small tubes which project through the upper portion ofthe magazine 18 and are submerged at their lower ends in the disinfecting liquid within the magazine. The fumes from the disinfecting material may escape from within the magazine 18 into the trough 2 through the passages formed by the nozzles 19, and the escape of such fumes may be hastened or augmented by playing a stream of air across the outer end of the nozzle 19 from an associated air nozzle 20, thereby creating a suction action through the nozzle and aconsequent discharge of the disinfecting liquid in finely broken-up or vaporized'form within the trough 2. The air nozzles 20 project, in the present instance, from a common tube or manifold 21, which is disposed within the trough 2 over the magazine 18. The air tube 21 has communication with the cylinder 22 of an air pump through a connecting tube The plunger 24 of the pump has its rod connected to an arm 25 that is loosely moimted on the shaft 14;, said arm 25 being fixed to a disk 26 which is also loose on said shaft. A spring 27 encircles the shaft let, and has its ends projecting laterally from the shaft with one end anchored to a side of the boxing 6, as at 28, and its other end secured to a pin 29 projecting from a side of the arm 25, the tension of the spring 27 urging the arm 25 in a direction to force its plunger 2% down into the pump cylinder 22. Upon a raising of the seat 3 an arm 30, that is fixed to the shaft 14 at the inner side of the disk 26, bears against a pin 31 on said disk to effect a movement of the disk and arm 25 in a direction to raise the pump plunger against the tension of the spring 27. When the seat has been completely raised, the disk 26 will have been turned a sufficient distance for a tooth 32 on a dog 33 to drop into engagement with a shoulder 34 on the peripheral portion of the disk. The dog 33 is carried by a portion of the bracket member 35 that carries the pump cylinder 22. The dog 83 now holds the disk 26 and attached parts against back turning under the tension of the spring 27 until the arm 30 has turned back a suflicient distance for its end to have cam engagement with the nose of the dog 33 and force such dog from looking engagement with the shoulder 34: of the disk, said releasing of the dog taking place at the limit of downward movement of the seat. Upon a releasing of the disk 26 the spring 27 forces the plunger 2 1 into thepump cylinder and causes a discharge of air from the air nozzles 20 of the manifold 21 and a consequent discharge of the disinfectant in vaporized form into the trough 2 from the magazine 18. It

is preferable to so direct the air discharge from'the nozzles 21 that the discharge from the several nozzles is in the same olirection around the interior of the trough 2, as inclicated by the position of the nozzles in Fig. 1.

The disinfectant is contained in a receptacle 36, which may be located in any desired position adjacent to the closet bowl, and has a discharge tube 3'? leading from the bottom thereof to the top portion of a cylindrical valve case 38, which loosely encircles the shaft 13 in concentric relation thereto. A rotary valve 39 is fixed to the shaft 13 within the valve case 38 and is provided with a socket 40 in the periphery thereof, which socket, when the seat is down, is out of register with the outlet end of the tube 37, and when the seat is raised into turning position is in register with the outlet end of said tube 37 to permit a measured quantity of liquid toflow therein from the tube 37. then the seat is in lowered position the socket 40 is inclined downward and in register at its outer end with an outlet passage. 41 in the valve case 38, whereby the liquid in the socket 4:0 is permitted to flow through said outlet passage and a tube 42, which leads therefrom to the magazine 18. It is thus evident that the supply of disinfectant liquid within the magazine 18 is replenished each time the seat is raised to turning position and then lowered. In order to maintain a close seating of the valve against the casing 38 around the inlet passage 37 when the valve is in normal at-rest position, a spring-pressed valve member 48 is set into thevalve 39 and held outward in closing contact with the marginal wall of the inlet fluid passage of the casing by a spring 4st. The container 16 may be provided in its top with a vent as for the escape of air therefrom.

It will be understood in the use of our invention that the disinfecting fumes or vapor discharged from the magazine 18 will circulate freely entirely around the interior of the trough2 and come in contact with all portions of the seat exposed to the interior of the trough, thereby disinfecting the un der surface of the seat preparatory to subsequent use after the seat has been raised and turned over.

We wish it understood that our invention is not limited to any specific construction, arrangement or form of the parts, as it is capable of numerous modifications without departing from the spirit of the claims.
